Commentary by TKV Desikachar:
“The next six chapters emphasise that
devotion is the basis for seeing the truth.
This truth is, the Lord.
But devotion must grow from following ones duty
in a spirit of selflessness and search.”
– TKV Desikachar on Gītārtha Saṃgraha of Śrī Yāmunācārya Śloka Three
(Yāmunācārya overview of the Bhagavad Gītā Chapters Seven to Twelve)
“The Lord cannot be described in words.
But appears here for our aid.
The devotee can recognise this.”
